1 Series BDF Serial ASCII LARGE DISPLAYS for Serial ASCII BDF-xx-S repeater for Serial ASCII IDEAL SOLUTION for reading ASCII messages at long distances, addressable units controlled through standard protocols RS232, RS485, R422,... Very strong housing and electrically protected units, designed for all type of industrial applications.

2 The BDF series of large displays for Serial ASCII signals is a standard ASCII code repeater, accepting messages in the most common protocols in industry (RS232, RS485, RS422, TTL,...). The transmission baudrate is selectable and the units can be addressed independently. Model BDF Serial ASCII LARGE DISPLAYS for Serial ASCII The mechanical of the BDF instruments is a very strong and sturdy aluminium housing anodized in black color, for panel mount, and for wall mount as an option. The front lens is antirreflexive and is firmly inserted on the aluminium profile with a rubber gasket around, providing IP65 protection on the front. It allows display of numerical characteres with and without decimal point, and a selection of other characters («A», «b», «C»,...) easily displayed and recognized within a 7 segment led. Several units can be connected to the same data bus and be controlled independently. Up to 32 different addresses can be configured and address «0» allows the instrument to read and display all the data transmitted on the bus. The signal wires are connected to plug-in screw clamps for higher security of the connections, accesible at the rear side of the instrument. The power is connected to a 3 terminal plug (2 power connections and 1 earth) containing an integrated protection fuse and an additional fuse as spare part. 0.- ORDERING REFERENCE BDF Size Model Power Color Protocol 24 S 230 Vac R - Red RS Vac RS Vdc RS TTL SIZES SIZE BDF-24.- Instrument with 4 digits 57mm (2,3 ) digit height SIZE BDF-26.- Instrument with 6 digits 57mm (2,3 ) digit height SIZE BDF-44.- Instrument with 4 digits 100 mm (4,0 ) digit height SIZE BDF-46.- Instrument with 6 digits 100 mm (4,0 ) digit height 2.- GENERAL CHARACTERISTICS DISPLAY READING HOUSING 4 or 6 digits 7 segment led red color digit of 57mm height (2,3") or digit of 100mm height (4,0") from «-9999» to «9999» or from « » to «999999» decimal point selectable extruded aluminium anodized in black color panel mount (optional wall mount) FRONT POWER CONSUMPTION Working Temp.

3 1 2 3 N/C 3.- FRONT AND REAR VIEW D7 D4 D3 D2 D1 D7 D6 D5 D4 D3 D2 D1 Polarity Overrange Polarity Overrange Decimal Points Signal Input Power (fuse included) The instruments from the BDF Series are available in 4 and 6 digit format. All digits are led 7segment type, with decimal point selectable. POLARITY AND OVERRANGE SYMBOLS Digit «D7» controls the polarity segment («-») and the overrange point («.»). The polarity segment activates when D7 is a character with central segment active («H», «4», «6»,...). The overrange point activates when «D7» is a character with upper segment active («0», «7»,...). If «D7» contains both central and upper segments («8», «P»,...) both the overrange and the polarity will light. Note. - Units with 4 digits must receive also digits «D5», «D6» and «D7» to activate Polarity and/or Overrange. 4.- WORKING MODE (SHIFT, STROBE) AND ADDRESSING THE INSTRUMENT GENERAL WORKING MODE.- the character received is placed in the internal buffer, at the least significant position («D1») and moves all existing characters in the buffer to the left. Character «D7» is lost, and is subtituted by character at «D6». New characters arriving will be placed on «D1» and all other existing characters will be moved to the left. MODE «STROBE».- The characters stored in the buffer are loaded on display when a «CR» character is received. MODE «SHIFT».- The characters stored in the buffer are always being displayed. Note.- if working on «SHIFT» mode a «CR» character is received, the next character received will clean both the buffer and the display and will place the character received on display «D1» Note.- Characters which can not be ASCII displayed, will not be displayed on the instrument. Instruments with 4 digits still have «D5» and «D6» in the internal buffer, although only «D1», «D2», «D3», «D4» and «D7» are displayed. ADDRESS.- Address for instruments BDF Serial are selected with internal minidips (see section 8). Possible addresses are 1 to 31 (total of 31 differente addresses). The instrument will receive all data transmitted on the line, but will only display data which has the byte address the same as his address. Address «0» is a SNIFFER function, which will make the instrument to display all data from all addresses which are transmited on the line. Note.- The instrument with address 0 will display the address byte as a standard ASCII code. 5.- CONNECTIONS FOR POWER SUPPLY The power connector allows one terminal for earth and two power terminals. Internal fuse is integrated on the connector and an additional fuse is available as a spare part. The value of the fuses depends on the power supply, and is according to rule IEC127/2 230 Vac ma fuse time-lag 115 Vac - 400mA fuse time-lag 24 Vdc ma fuse fast Powered 230 Vac (115 Vac optional) Fuse Powered 24 Vdc Isolated + -

5 7.- START-UP MESSAGE AND DATA FORMAT CONNECTING THE POWER SUPPLY.- When connecting the power supply to the instrument, the first message to appear on display is information on the current configuration of the unit. This message will dissappear in 3 seconds, and the display will read « ». The instrument remains «hearing» for new data coming through the line. D7 D6 D5 D4 D3 D2 D1 D7 Without information D6 Number of bits «7» or «8» D5 Parity «E» parity even «o» parity odd «n» without parity «I» parity ignored D4 Modo «F» mode shift «r» mode strobe D3 Reception «L» rec. state correct «H» rec. state not-correct Note.- take into consideration that a RS485 type can be tested as correct reception status although the polarity of the cables being inverted. D2 Address character from «1» to «O» (see sections 8 and 9) D1 Speed number from «0» to «7» (see section 8) DATA STRUCTURE.- The structure of the data to receive once the unit is «hearing», is the following : 1.- Reception of character «ETX» (or character «XOFF») 2.- Reception of character «STX» (or character «XON») 3.- Reception of address of the instrument (address from «0» to «31») 4.- Reception of DATA characters 5.- Reception of character «ETX» (or character «XOFF») MESSAGE FORMAT STX Address Data ETX 1 byte 1 byte n bytes 1 byte XON Address Data CR XOFF 1 byte 1 byte n bytes 1 byte 1 byte Note.- An «ETX» character (or «XOFF» character) is sent before starting the first message in order to clean the internal buffer. (The «ETX» character first loads the buffer values on display and then cleans the buffer) Note.- If working on STX/ETX mode, the «ETX» character already includes the «CR» character and its functionality is the same in «SHIFT» mode and in «STROBE» mode. Note.- If working on XON/XOFF mode, the «XOFF» character does not include the «CR» character. If working in «STROBE» mode a «CR» character is needed to load on display the buffer data.
